If you have anything to do with networked AV and you're not well-versed in the OSI model, we've got you covered. You will learn the fundamental ideas around getting data from host A to host B over a ...

The Open System Interconnect (OSI) network model, referred to by many as simply a stack, is in fact a well-designed, layered architecture for efficient intersystem and intrasystem communications. In ...

Getting a handle on the invisible part of your network—the protocols that are in use—can be of enormous value in helping you detect problems.

Layer 2 of the OSI model is where we find the Data Link Layer, which provides the mechanism by which data is transferred from node to node across a network.

I like to think of the transport layer as the layer of the OSI Model that enables more interesting traffic. While we network engineers may love a lot of the simpler uses of the IP protocol and ...

Strengthening the different layers of IT networks Getting started on designing a network is a task of formidable proportions, but all the more so if you are looking to build a secure network.

CSOI represents a forward-thinking shift in network security architecture. By introducing an identity-aware layer into the OSI model, it lets organizations, especially those reliant on legacy systems, ...

Open System Interconnection, a layered model for network transport and applications. For instance, the seventh layer in the OSI model—the Application layer—defines program to program communication, or ...
